An Empirical Analysis of Effects of Stress on Relation between Physical Activity and Health-Related Quality of Life: Results from KNHANES 2008 to 2013

Abstract In literature, empirical studies investigating how stress affects HRQOL (health related quality of life) through physical activities are insufficient. In this sense, on the basis of KNHANES dataset for 2008 ~ 2013, weconducted an empirical study. Empirical results revealed that in the male group with stress experience, HRQOL was significantly influenced by age, household income, education, occupation, physical activity level. To do so, we adaptthe chi-square analysis and the logistic regression analysis. Meanwhile, in the stress non-experience group, the lowlevel activity has lower HRQOL than the high level activity(male: OR=1.15 p<0.001, female: OR=1.18 p<0.001). In the stress experience group, the male has the same pattern of effect compared to the stress non-experience group(OR=1.79 p<0.01). However, in the female, the low level activity has the higher HRQOL than the high levelactivity(OR=1.18 p<0.05). Therefore, we confirmed that physical activity has a different effect on HRQOL throughstress experience.
